Rho (uppercase Ρ, lowercase ρ or ϱ; pronounced /ˈroʊ/) is the 17th letter of the Greek alphabet. In the system of Greek numerals, it has a value of 100. It is derived from Semitic resh "head". Its uppercase form is not to be confused with the Latin letter P, although both are typeset using the same glyph.

Rho is classed as a liquid consonant (together with lambda and sometimes the nasals mu and nu), which has important implications for morphology. In both Ancient and Modern Greek, it represents a trilled or tapped r.
In polytonic orthography a rho at the beginning of a word is written with a rough breathing (equivalent to h) — ῥ rh — and a double rho within a word is written with a smooth breathing over the first rho and a rough breathing over the second — ῤῥ rrh — apparently reflecting an aspirated or voiceless pronunciation in Ancient Greek, hence the various Greek-derived English words which start with rh or contain rrh.
The name of the letter is written in Greek as ῥῶ (polytonic) or ρω/ρο (monotonic).
Letters that arose from rho include Roman R and Cyrillic Er (Р).
The characters Ρ, ρ and ϱ are also used outside its Greek alphabetical context in science and mathematics.

()The letter rho overlaid with chi forms the Chi Rho symbol, used to represent Jesus Christ.
Former Rhodes Scholars are entitled to use the Greek letter rho as a designation of their status. When used, the symbol should precede the name.[1]
